  • Patent number: 7656371
    Abstract: A light emitting apparatus comprises at least two light emitting elements with different chromaticities; and a light emitting element controller that controls light emitted from the light emitting apparatus so as to be a desired chromaticity. The light emitting element controller controls the light emitting elements based on a predetermined function of light emitting element temperature variation. Accordingly, it is possible to provide a light emitting apparatus that, even if the temperature varies, has a stable desired chromaticity without chromaticity variation. In addition, since control is performed based on a property function of wavelength fluctuation due to light emitting element temperature variation, it is possible to provide more reliable reproduction characteristics, and a desired chromaticity.

  • Patent number: 7558471
    Abstract: A DVD recorder is provided which includes an NTSC decoder (15) for converting an NTSC-based TV signal into an ITU-R BT. 601-based video signal, an MPEG encoder (17) for encoding the ITU-R BT. 601-based video signal into an MPEG-2 data stream, a driver (23) for recording the MPEG-2-based data stream to a DVD disk, and a VBI slice circuit (24) for detecting VBI from the TV signal. When the V timing of an input signal is asynchronous with that of recording signal, the MPEG encoder (17) inserts null data as blanking data into an arbitrary frame if a frame repeat has occurred or deletes null data from blanking data from an arbitrary frame if a frame skip has occurred.

  • Patent number: 7333545
    Abstract: A decoder decodes full frame MPEG-2 video by a single method that applies regardless of buffer memory and frame rate conversion considerations. A display control module handles frame rate and field sequence in response to host configuration, trick play command signals, and information in the received bitstream. Pictures are decoded as buffer memory for the decoded pictures becomes available, and picture display attributes are assigned and stored in a table, one string for each decoded picture. Frame rate and field sequence are managed in light of memory constraints, to produce a high quality result without re-decoding data.
